  • Publication number: 20240014200
    Abstract: The present invention provides a method of relocating optical devices onto a carrier substrate in a case where a pixel pitch of a display is not an integer multiple of a pitch of the optical devices arrayed on a sapphire substrate. A moving speed ratio between a donor substrate and a receptor substrate is determined from an array pitch (3, 4) of optical devices (2) formed on the sapphire substrate and an array pitch (5, 7) of optical devices to be transferred onto a carrier substrate (6), and the optical devices are subjected to LIFT (laser transferred) in synchronization with movement of the donor substrate, whereby the optical devices on the sapphire substrate are transferred onto the carrier substrate at an array pitch that is identical to the pixel pitch of the display.
